' SPECIFICATION x'ormingpart of Letters Patent No. 351,585, dated October 26, 1886.

Application Elled'December 29, 1885. Serial No. 1787.004. (No model.) Patented in England February Q3, 1885, No, 2,422.

To all whont itv ina/y concern.-

Be it known that I, J AMEs BROWN EDMIS- TON, a subject of the Queen of Great Britain, residing at Liverpool, in the county of Lancaster, England, have invented a new and useful Condenser, (for which I have obtained a pat- `ent in Great Britain, No. 2,422 of'the year 1885, and nowhere else,) of which the following is a specification.

The invention relatesv to condensers mainly for use on board ship for condensing steam produced by distillation of sea-water, or from deck boilers or winches and like sources; and the object is to provide a condenserwhich shall be economical in construction, occupy comparatively small space, and have large and eiiicient cooling and condensing surfaces.

lIhe invention consists, generally, in a series of duplex or double-walled cellular condensercompartments contained in a casing or chamber and communicating with each other, in connection with means for causing the condensingwater to come in contact with all parts of the walls of the condenser-compartments, as hered inafter fully described. f

In practice I find the following construction answers well. A cylindrical cast-iron casing or chamber is fitted with covers at each end, and has openings for the inflow and outflow of water. The cellular compartments are preferably of sheet-copper, or double-walled, annular in shapeand superposed one on another within the case or chamber and from one to another. The spaces between the double walls communicate annularly from compartment to compartment and at each extremity by apipe or pipes with the steam supply and condensedwater outfiow. In use the steam from the supply enters the compartments or spaces between the double walls, and cold water iiows through the casing within and around the annular condenser-compartments.

In the drawings, Figure l is a vertical section, partly in full lines; and Figs. 2 and 3 are cross-sections of the condenser, showingthe cellular compartments having two different forms of corrugated walls. 1

The cylindrical cast-iron chamber a is carried on a base, b, forming a reservoir for condensed water and the bottom cover of the con- Lterior walls of the compartments.

denser, c being the top cover thereof. The covers and chambers are bolted together or otherwise attached, as may be found desirable.

d is theintlow-opening, and e the discharge- Opening, for the condensing-water.

Each cellular compartment 7c is formed of double or exterior and interior walls, fg, preferably of sheet copper brazed together, as shown at 7L. If preferred, the walls may be bolted together.

t' are ferrules'or pieces for keeping the compartment-walls at the required distance apart.

The compartments, 7c, formed by the double walls are Supported one on another and connectedtogether by brazed or soldered joints, as shown at j, and when fitted together a series of these cellular steam compartments la connected by annular spaces k are formed.

Zv are the steam-inlet pipes opening into the top steam-compartment, and m are condensedwater pipes leading from the bottom compartment into the condensed-water reservoir forming the base b. Diaphragm-plates n are secured to carrying-bars 0 within the water-chamber a, and extend out between the compartments k, the said diaphragm-plates tting between the compartments, So as to cause the condensing-water to pursue a zigzag path through the .chambera and come incontact with every portion of the exterior walls of the condensercompartments k. A pipe, p, leads from the lower part of the chamber a up within the central space formed by the interior walls, g, of the condenser-compartments k. The said pipe is closed to the top, and has perforations or openings q at regular intervals, so that the condensing-water in passing through the pipe will be projected against every portion of the inrior and exterior walls of the compartments k are connected together at the ends by the threaded tubes and nuts r. The arrows show the direction of motion of the steam and condensing-water.

At sthe compartment-walls are shown radially, and at t annularly corrugated or fiuted, the saidwalls being corrugated or uted to present a greater surface for contact of the condensing-water with the walls of the steam-condensing compartments k.

The inte-` Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. In condensers, the combination, with the Water-chamber a, having the inlet and outlet ports d e, of the series of annular condensercompartments lc, formed of exterior and interior walls, 7 g, the steam-inlet pipes l, the condensed-wateroutlet pipes m, and the base I), forming a condensed-Water reservoir, substantially as and for the purposes set forth.

2. In, condensers. the combination of the water-chamber u, the series of annular condenser-compartnients 7c, formed of the exterior and interior Walls, 7" g, and the diaphragmplates a, extending inwardly between the coinpartlnents, substantiall)T as and for the purposes set forth.

3.` In com'lensers, the combination of the waterehamber a and the Series of annular double-walled condenser-eompartments k therein, the interior and exterior walls ofsaid eoxnpnrt ments being corrugated or iiuted, substantiel ly as and for the purposes set forth.

4. In condensers, the combination of the Water-chamber a, the series of double-Walled condenser'compartments k therein7 and the Weten pipe p, extending up into the interior Waterspaee of the condenser and perforated at intervals, substzmtially as and for the purposes set forth.

5. In eondensers, the combination ofthe water-chamber a, the series of double-Walled condenseneonipartments k, formed of exterior and interior Walls, f g, and the tubes r, connecting said Walls at the ends, substantially ns and for the purposes set forth.

6. In condensers, the annular condensercompartments k, formed of exterior and inte rior Walls, f g, in combination with ferrules i, to hold said walls apart, substantially as set forth.
